PROBLEM TO BE SOLVED: To provide a reliability assessment method and a reliability assessment program for quantitatively assessing the reliability of provided structural members. SOLUTION: The reliability assessment method is for assessing the reliability of provided structural members. It comprises a process of measuring crack depth of a certain number of structural members among a plurality of structural members to be assessed, a process of calculating a plurality of stress ranges working on the structural members from the crack depth by using the crack progression rule, a process of statistically processing a plurality of stress ranges and calculating statistical distribution of the stress ranges, a process of calculating crack depth distribution at an arbitrary time point by using Monte-Carlo method from the statistical distribution, a process of calculating failure probability based on the fraction of crack depth exceeding a limit value from the crack depth distribution, and a process of calculating the assessment value of reliable section from the failure probability.
